Description

An assembly type manhole}

The present invention relates to a toilet cleaning room for cleaning work, and more particularly, it is very easy to handle and install on-site, and significantly reduces the construction period, thereby preventing traffic obstacles, and can be repaired quickly in case of damage. It is related with the cleaning unit toilet for prefabricated pipe washing operation which became easy to manage.

In general, a manhole is a work space that a worker can enter and exit to maintain underground sewer pipes, water pipes, underground cables, and the like. These manholes form a reinforcing frame in the construction site, and form a formwork on the outside of the reinforcing frame, and then cast concrete in the form of the form to form a cylindrical body having an opening at the top, The cover plate is installed in the upper opening of the main body.

However, in order to construct a conventional manhole, it is necessary to construct a frame and formwork on the site, and to cure concrete for a relatively long period of time, so that a construction period in accordance with the frame and formwork and concrete curing is required. Accordingly, there is a problem in that traffic is controlled for a long time or interferes with vehicle communication.

In order to solve this problem, a manhole is pre-fabricated in concrete and transported to the site for construction. However, in this case, since the manhole itself is bulky and heavy, there are problems such as requiring additional heavy equipment for loading and unloading and on-site installation work. In addition, the conventional manhole, if a part is broken, it is inevitable for long-term traffic control due to the rehabilitation of the damaged part and the concrete curing, there is a problem such as post-maintenance is inconvenient.

The present invention has been proposed in view of the problems described above, the purpose of the present invention is very easy to handle and on-site construction, while significantly reducing the construction period to prevent traffic obstacles, and can be quickly repaired in case of damage In order to provide a prefabricated tubing cleaning chamber for easy post maintenance.

According to the present invention, an opening 11 is formed at an upper end thereof, and is embedded in the ground 5, and a cylindrical main body 10 in which a cleaning tool 2 connected to the underground pipe 1 is received therein. In the cleaning compartment close-up comprising a cover plate 15 to cover the opening 11 of the upper end of the main body 10, the main body 10 is divided into a plurality of unit bodies 30, the unit body 30 ) Is laminated in the vertical direction, the coupling grooves 35 and the engaging projections 38 which are engaged with each other are formed on the joint surfaces of the upper and lower units 30 stacked on each other, at least among the unit 30 One unit 30 is provided with a cleaning manifold for the prefabricated tubing cleaning, characterized in that the through-hole 45 is formed so that both ends of the pipe (1) is passed through.

According to another feature of the present invention, the unit 30 is provided with a manifold for cleaning the prefabricated pipe washing operation, characterized in that molded into a waste synthetic resin.

According to another feature of the present invention, a separate sealing member 45 is interposed on the connection surface of the upper and lower units 30 to be positioned outside the coupling groove 35 and the coupling protrusion 38. A prefabricated cleaning lavatory toilet is provided.

Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows.

1 is an exploded perspective view of the present invention, Figure 2 is a cross-sectional view of the present invention. As shown, the present invention is buried in the ground and the inside of the tubular body 10 to accommodate the cleaning tool (2) connected to the underground pipeline (1), and the upper end of the main body 10 The cover plate 15 is installed in the same as in the prior art, the main body 10 is formed by stacking a plurality of unit pieces 30 divided in a vertical direction, at least one of the unit body 30 to the cleaning Through-holes 45 through which both ends of the sphere 2 pass are formed.

The unit 30 has a lower unit 30 having a bottom surface 31 formed at a lower end thereof, a plurality of ring-shaped intermediate units 30 stacked on the upper end of the lower unit 30, and the intermediate units The upper unit 30 is formed on the top of the 30 and the central portion has an opening 11 on which the cover plate 15 is placed.

Coupling grooves 35 and coupling protrusions 38 that are engaged with each other are formed on surfaces of the unit bodies 30 that are in contact with each other, such that the unit units 30 stacked in the vertical direction are not separated from each other by an external force. Preferably, the unit 30 is molded to various heights, so that it can be installed in accordance with the height of the construction site.

At this time, the concave groove 6 is formed in the connection surface of the unit body 30 so as to be located outside the coupling groove 35 and the coupling protrusion 38, the sealing member 45 in the concave groove (6) Is interposed. The sealing member 45 is made of water-expanded rubber that is expanded by water, and prevents water from flowing out to the joint surfaces of the upper and lower units 30 stacked on each other.

On the other hand, since the plurality of units 30 are formed by recycling the waste tires, the weight is considerably lighter than general concrete products. In addition, the pressure resistance is excellent even under the load along the traffic.

Therefore, the present invention, unlike the conventional construction, which takes a lot of construction period due to the frame and formwork and concrete curing, the main body 10 is divided into a plurality of upper and lower units 30, the unit 30 in the field Since it can be laminated in construction, the construction work is not only quick and easy, but also prevents traffic obstacles due to long-term control of the vehicle.

In addition, since a plurality of unit pieces 30 divided into small sizes can be transported and installed on site, loading, unloading, and construction work are much easier than in the related art. In particular, since the unit 30 is made of polyethylene (PE) synthetic resin by recycling waste tires, since the weight is considerably lighter than that of general concrete products, such loading, unloading, and installation work is easier, as well as vehicle traffic. Since the pressure resistance that can withstand the load at the time is superior to the concrete product, the structural strength can be improved. In addition, the present invention, if a part is broken, since only the broken unit 30 need to be replaced, post-maintenance is made quickly and easily. Furthermore, the present invention recycles waste tires, which is advantageous in terms of economics and environmental protection.

Preferably, as shown in Figure 2, between the interior of the main body 10 and the cleaning tool (2) is provided with a heat insulating material made of urethane foam, the cleaning tool (2) by the heat insulating material (4) By keeping the warmth, the cleaning tool 2 is to prevent the freezing in extreme conditions such as the temperature sharply dropped in the winter.

On the other hand, the cleaning pipe (7) connected to the upper port (2a) of the cleaning tool (2) is removed after the tub washing operation, the branch pipe, etc. not shown separately in the upper port (2a) of the cleaning tool (2) Will be connected.

As described above, the present invention can be constructed by directly stacking a plurality of divided units in the field, thereby preventing traffic obstacles for a long time, and carrying and installing a plurality of divided units in a small size on site. Since the unit is molded of synthetic resin and light in weight, it is very easy to load, unload, and install the site, and only partially replace and install the damaged unit, so that post-maintenance can be performed quickly and easily.
